运煤系统各区域粉尘防爆分区研究

Research on Dust Explosion Prevention Zones in Various Areas of Coal Handling System

本文依据GB 50058—2014《爆炸危险环境电力装置设计规范》,对火力发电厂运煤系统各区域的粉尘防爆分区进行研讨,并对运煤系统各主要设备所在的防爆区域提出建议,以供火力发电厂运煤系统防爆分区设计选型时参考。

Based on the"Code for Design of Electrical Installation in Explosive Atmospheres"(GB 50058-2014),this article discusses the dust explosion-proof zones in various areas of the coal handling system of fossil-fired power plants,and puts forward suggestions for the explosion-proof zones where the main equipment of the coal handling system is located,for reference in the design and selection of explosion-proof zones for coal handling systems in thermal power plants.
